Pursuant to 35 U.S.C. §119(a), this application claims the benefit of earlier filing date and right of priority to Korean Application No. 10-2013-0081136, filed on Jul. 10, 2013, the contents of which are hereby incorporated by reference herein in their entirety.
Field of the Invention
The present invention relates to a mobile terminal, and more particularly, to a mobile terminal and controlling method thereof. Although the present invention is suitable for a wide scope of applications, it is particularly suitable for facilitating a terminal to be used in further consideration of user's convenience.
Discussion of the Related Art
A mobile terminal is a device which may be configured to perform various functions. Examples of such functions include data and voice communications, capturing images and video via a camera, recording audio, playing music files and outputting music via a speaker system, and displaying images and video on a display. Some terminals include additional functionality which supports game playing, while other terminals are also configured as multimedia players. More recently, mobile terminals have been configured to receive broadcast and multicast signals which permit viewing of contents, such as videos and television programs.
Generally, terminals can be classified into mobile terminals and stationary terminals according to a presence or non-presence of mobility. And, the mobile terminals can be further classified into handheld terminals and vehicle mount terminals according to availability for hand-carry.
There are ongoing efforts to support and increase the functionality of mobile terminals. Such efforts include software and hardware improvements, as well as changes and improvements in the structural components which form the mobile terminal.
Particularly, the hardware performance enhancement of a terminal diversifies types of sensors provided to the terminal. Yet, although sensor types are diversified, since a terminal usually uses a specific sensor singularly, utilization of sensors stays on a low level. Moreover, signals detected by sensors are handled as noise unless a specific function is enabled. Hence, various types of sensors fail to meet utilization of sensors.
Recently, in order to further enhance sensor utilization, sensors of various types tend to be used compositively/synthetically. A terminal detects and learns a user's terminal use pattern by using/analyzing sensing signals sensed by sensors of various types synthetically and then determines a user's intention from other sensing signals detected later.
However, a terminal should minimize its power consumption to meet the demand for portability of the terminal. As mentioned in the foregoing description, if sensing signals detected from various sensors are detected and analyzed all the time, it may possibly cause power consumption.
Thus, in order to minimize power consumption despite utilizing various sensors actively, the demand for a method of controlling powers of sensors effectively is rising.
Accordingly, embodiments of the present invention are directed to a mobile terminal and controlling method thereof that substantially obviate one or more problems due to limitations and disadvantages of the related art.

The image frames processed by the camera 121 can be stored in the memory 160 or can be externally transmitted via the wireless communication unit 110. Optionally, at least two cameras 121 can be provided to the mobile terminal 100 according to environment of usage.
The microphone 122 receives an external audio signal while the portable device is in a particular mode, such as phone call mode, recording mode and voice recognition. This audio signal is processed and converted into electric audio data. The processed audio data is transformed into a format transmittable to a mobile communication base station via the mobile communication module 112 in case of a call mode. The microphone 122 typically includes assorted noise removing algorithms to remove noise generated in the course of receiving the external audio signal.
The user input unit 130 generates input data responsive to user manipulation of an associated input device or devices. Examples of such devices include a keypad, a dome switch, a touchpad (e.g., static pressure/capacitance), a jog wheel, a jog switch, etc.
The sensing unit 140 provides sensing signals for controlling operations of the mobile terminal 100 using status measurements of various aspects of the mobile terminal. For instance, the sensing unit 140 may detect an open/close status of the mobile terminal 100, relative positioning of components (e.g., a display and keypad) of the mobile terminal 100, a change of position of the mobile terminal 100 or a component of the mobile terminal 100, a presence or absence of user contact with the mobile terminal 100, orientation or acceleration/deceleration of the mobile terminal 100, and free-falling of the mobile terminal 100. As an example, consider the mobile terminal 100 being configured as a slide-type mobile terminal. In this configuration, the sensing unit 140 may sense whether a sliding portion of the mobile terminal is open or closed. Other examples include the sensing unit 140 sensing the presence or absence of power provided by the power supply 190, the presence or absence of a coupling or other connection between the interface unit 170 and an external device. And, the sensing unit 140 can include a proximity sensor 141.

The display 151 is typically implemented to visually display (output) information associated with the mobile terminal 100. For instance, if the mobile terminal is operating in a phone call mode, the display will generally provide a user interface (UI) or graphical user interface (GUI) which includes information associated with placing, conducting, and terminating a phone call. As another example, if the mobile terminal 100 is in a video call mode or a photographing mode, the display 151 may additionally or alternatively display images which are associated with these modes, the UI or the GUI.
The display module 151 may be implemented using known display technologies including, for example, a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light-emitting diode display (OLED), a flexible display and a three-dimensional display. The mobile terminal 100 may include one or more of such displays.
Some of the above displays can be implemented in a transparent or optical transmittive type, which can be named a transparent display. As a representative example for the transparent display, there is TOLED (transparent OLED) or the like. A rear configuration of the display 151 can be implemented in the optical transmittive type as well. In this configuration, a user is able to see an object in rear of a terminal body via the area occupied by the display 151 of the terminal body.
At least two displays 151 can be provided to the mobile terminal 100 in accordance with the implemented configuration of the mobile terminal 100. For instance, a plurality of displays can be arranged on a single face of the mobile terminal 100 in a manner of being spaced apart from each other or being built in one body. Alternatively, a plurality of displays can be arranged on different faces of the mobile terminal 100.
In case that the display 151 and a sensor for detecting a touch action (hereinafter called ‘touch sensor’) configures a mutual layer structure (hereinafter called ‘touchscreen’), it is able to use the display 151 as an input device as well as an output device. In this case, the touch sensor can be configured as a touch film, a touch sheet, a touchpad or the like.
The touch sensor can be configured to convert a pressure applied to a specific portion of the display 151 or a variation of a capacitance generated from a specific portion of the display 151 to an electric input signal. Moreover, it is able to configure the touch sensor to detect a pressure of a touch as well as a touched position or size.
If a touch input is made to the touch sensor, signal(s) corresponding to the touch is transferred to a touch controller. The touch controller processes the signal(s) and then transfers the processed signal(s) to the controller 180. Therefore, the controller 180 is able to know whether a prescribed portion of the display 151 is touched.

In case that a user attempts to take a picture of the user (self-photography) using the camera 121′, the mirror 124 enables the user to view user's face reflected by the mirror 124.
An additional audio output unit 152′ can be provided to the backside of the terminal body. The additional audio output unit 152′ is able to implement a stereo function together with the former audio output unit 152 shown in
A broadcast signal receiving antenna 116 can be additionally provided to the lateral side of the terminal body as well as an antenna for communication or the like. The antenna 116 constructing a portion of the broadcast receiving module 111 shown in
Referring to
A space for mounting such an external part as the battery loading unit 104, the USIM card loading unit 105, the memory card loading unit 106 and the like can be provided to a surface of the rear case 102. Generally, the external part loaded on the surface of the rear case 102 is provided to extend functions of the mobile terminal 100 in order to meet the diversified functions of the mobile terminal and a variety of the consumer's needs.
As the performance of the mobile terminal gets diverse, the battery 191 can be configured as a replaceable type, as shown in
The USIM card loading unit 166 or the memory card loading unit 167 may be provided, as shown in
Although
The rear cover 103 covers the surface of the rear case 102. Hence, the rear cover 103 can fix the battery, 191, the USIM card, the memory card and the lime not to be separated from the rear case 102 and also protects the external parts from external shocks or particles. Recently, a waterproof function is added to the mobile terminal 100. In order to prevent the external parts from contacting with water, the mobile terminal 100 can further include a waterproof structure (not shown in the drawing). Hence, when rear case 102 and the rear cover 103 are connected to each other, the waterproof structure can seal up the gap between the rear case 102 and the rear cover 103.
Nowadays, in the flood of information, the technology of selecting necessary and accurate information and analyzing the selected information is mandatory. In particular, as the types of sensors provided to a terminal get diversified, sizes of sensing signal informations detected by the diversified sensors are not negligible. Thus, the demand for a method of sorting necessary signals from the rapidly increasing sensing signals and effectively analyzing the sorted sensing signals is rising.
According to one embodiment of the present invention mentioned in the following description, a following method is proposed. First of all, a user's terminal use pattern is analyzed in a manner of compositively analyzing sensing signals detected by various sensors. Secondly, a user's intention of using a terminal in the future is estimated based on a result of the analysis. In particular, in order to provide a service suitable for a situation of each single user, the present invention proposes to analyze a user pattern by individually controlling operations of several sensors per place and time.
Moreover, according to one embodiment of the present invention, in controlling a power of each of a plurality of sensors, proposed is a method of determining whether to control each power through a user's use pattern. In particular, based on a use pattern learned per place and time, a power of each of a plurality of sensors is selectively controlled. Thus, a power consumption of a terminal can be effectively operated and managed. And, a user's terminal use pattern can be updated through an additional detection of user environment information.
In the following description, controlling methods, which can be implemented in the above-configured mobile terminal, according to embodiments of the present invention are explained with reference to the accompanying drawings.
A control operation in an existing method shown in
First of all, in a step S501, the mobile terminal 100 activates its sensors all the time. Alternatively, the mobile terminal 100 may activate a sensor in response to a user's command. In a step S502, the mobile terminal 100 analyzes/recognizes a circumstance by utilizing the activated sensors. Subsequently, in a step S503, the mobile terminal 100 analyzes a user's use pattern. In this case, the user's use pattern may include at least one of an information on an application activated per user's place and time, an information on an occurring event per user's place and time, an information on a changed setting value per user's place and time and the like.
In a step S505, a server obtains a location of the mobile terminal 100 and then determines whether the location of the mobile terminal 100 enters a new place (or a new location). As a result of the determination, if the mobile terminal 100 is situated not at a new location but at a previously entered location, the server can go to a step S507. As a result of the determination, if the mobile terminal 100 enters the new location, the server collects a user's use pattern in a step S506. In doing so, the collection of the user pattern can be performed in a manner that the former use pattern collected by the mobile terminal 100 in the step S503 is delivered to the server. In the steps S505, the server can record the collected user's use pattern in a manner of creating a database (DB) and placing it on the created database.
In the step S507, the server compares a sensed signal to the user pattern database (DB). If a pattern matching a sensing signal sensed by the mobile terminal 100 exists in the use pattern DB, the server can notify/recommend a service according to the use pattern to the user [S504].
According to the method described with reference to
Referring to
In the step S501-1, the server can determine whether a remaining power of the mobile terminal 100 is sufficient. The determination of a presence or non-presence of the sufficient remaining power can be performed in a manner of comparing a remaining power retained by the mobile terminal 100 to a power consumed in collecting the use pattern. For instance, when a level of the remaining power is 20%, if a level of the power consumed in collecting the use pattern is determined as about 10%, a level of the remaining power after use pattern collection becomes 10% only. Hence, the server can determine that the remaining power is not sufficient. If the server determines that the remaining power is not sufficient, the server can go to the step S506.
If the server determines that the remaining power is sufficient, the server can go to the step S501-2. In the step S501-2, the server can transmit a control command for activating a sensor to the mobile terminal 100.
According to the above descriptions of the existing method and the embodiment of the present invention with reference to
As mentioned in the foregoing description with reference to
One example for the server to perform an operation of determining the remaining power level in the above-mentioned step S501-1 is described in detail with reference to
If the event 601 at the 1st place is exemplarily analyzed, it may indicate that the charging event has regularly occurred in the specific time slot 1300˜1700 at the specific place ‘1st place’.
Assuming a case that the server stores the above-mentioned use pattern DB, a case that the mobile terminal 100 enters the 1st place is described as follows. First of all, if the mobile terminal 100 triggers the charging event by entering the 1st place, the server can calculate a remaining power level of the mobile terminal 100. For instance, assume that the calculated remaining power level of the mobile terminal 100 is 60%. The server can select a most appropriate circumstance cognitive level based on the calculated remaining power level. In this case, the circumstance cognitive level indicates an extent of dividing accuracy in recognizing a circumstance into several levels. If the level gets higher, recognition can be performed more accurately by consuming a more power. If the level gets lower, recognition can be performed less accurately by consuming a less power. In particular, if the circumstance cognitive level is the highest (hereinafter, a highest level case is represented as a 1st level and other cases next to the highest level case in order shall be represented as a 2nd level, a 3rd level and so on), circumstances are sensed by activating all of the included sensors as many as possible and the sensed results are then analyzed. As the circumstance cognitive level gets lower gradually, the sensors consuming high powers are sequentially deactivated (disabled). Hence, it is able to derive a recognition result of somewhat low accuracy with reduced power consumption. When a remaining power level is 60%, if a circumstance cognitive level is set to the highest level (i.e., 1st level), since a half of the remaining power level should be consumed, it may be determined as inappropriate. Hence, if the server detects the remaining power level of 60%, the server can set the circumstance cognitive level to the 2nd level (or lower). If the circumstance cognitive level is set to the 2nd level, the server notifies this setting result to the mobile terminal 100. If so, the mobile terminal 100 is able to control the powers of the sensors based on the received setting result. In particular, the mobile terminal 100 can activate/deactivate (enable/disable) a plurality of sensors to correspond to the 2nd level.
If the mobile terminal 100 controls the powers of the sensors in response to setting the circumstance cognitive level to the 2nd level, the mobile terminal 100 recognizes the circumstance by utilizing the activated sensors and is then able to make a report to the server again. If the server receives the report of the circumstance from the mobile terminal 100, the server adds a new circumstance to a previously saved use pattern DB and updates the use pattern DB.
As a count of updating the use pattern DB is incremented, the updated use pattern DB can enable a user's use pattern to be analyzed more accurately.
Meanwhile, according to one embodiment of the present invention, in setting a circumstance cognitive level, it is intended to provide a user environment for setting the circumstance cognitive level per specific area. Such an embodiment shall be described with reference to
Referring to
If a user selects the aforementioned consumption level indicator, the user is able to set a circumstance cognitive level for a selected point. In particular, if the controller 180 receives an input (e.g., an input of touching the consumption level indicator 701-a) of selecting a prescribed consumption level indicator, the controller 180 can output a popup window 702 for setting a circumstance cognitive level. If the user selects a prescribed level from the popup window 702, the user may be able to set a circumstance cognitive level for a corresponding point.
For a specific point, if a circumstance cognitive level is set, referring to
Moreover, an indicator 703 for identifying the selected point can be displayed on the map screen together with the popup window 704.
As mentioned in the above description, while the circumstance cognitive level is set for the specific area, if the mobile terminal 100 enters the corresponding area, the controller 180 controls powers of sensors by the 2nd level setting set up by the user and is able to detect a user's use pattern.
Meanwhile, in detecting a use pattern, there may be a difference between an estimated power consumption amount and an actual power consumption amount. Therefore, according to one embodiment of the present invention, it is proposed that the controller 180 provides the actual power consumption amount to a user.
The per-item use rates may include a power rate consumed for a display, a power consumption rate in a phone call standby mode, and the like. And, it is able to display a power rate consumed for an actually performed use pattern detection in accordance with the circumstance cognitive level set in
Meanwhile, according to the settings in the above-described embodiment, an estimated power consumption is 20%. Yet, as can be observed in the status diagram shown in
According to embodiments of the present invention, a user's use pattern of the mobile terminal 100 is analyzed to estimate a user's intention in the future. Based on the estimated user's intention, the controller 180 is proposed to provide an environment for enabling a user to perform a corresponding operation with ease. Such an environment is described in detail with reference to
An operation according to one embodiment of the present invention can be divided into a step of learning a use pattern and a step of utilizing the learned use pattern. In particular, as mentioned in the foregoing description, the use pattern learning step should consider a remaining power level to minimize waste of power. The two steps are described in detail as follows.
In order to learn a use pattern, the controller 180 can set a circumstance cognitive level based on a user's input or a remaining power level. As mentioned in the foregoing description, the circumstance cognitive level means an extent of discriminating accuracy in recognizing a circumstance. In detecting a use pattern in which a user moves on foot in a specific time slot every morning, the controller 180 may mainly use sensors for detecting a location of the mobile terminal. In particular, if a remaining power level is determined as sufficient, the controller 180 can accurately determine a location variation of the mobile terminal 100 by utilizing a GPS sensor. As a user's specific time/location use pattern, the controller 180 can detect the actions 1) to 4) in the above-described example. The controller 180 reports the detected use pattern to a server and is able to create a database of the detected use pattern.
According to one embodiment of the present invention, as mentioned in the foregoing description with reference to
If a user enters a corresponding area by carrying the mobile terminal 100, the controller 180 can automatically control sensors to be activated/deactivated (enabled/disabled) depending on preset conditions. The controller 180 detects a user's use pattern using the activated sensors and is then able to report the detected use pattern to a server.
For another example, assume that the controller 180 detects a user's call use pattern in a corresponding area. In particularly, it is intended to describe one example for a following method. First of all, the controller 180 recognizes a user's voice in a user's call use pattern. Secondly, a recommended content is provided to the user based on a result of the corresponding voice recognition.
The controller recognizes a call voice in a user's call use pattern, extracts a keyword from the recognized call voice, and is then able to determine a user's interesting field based on the extracted keyword. For instance, if a keyword for ‘President LEE Myung Bak’ is extracted from a user's call keyword, the controller 180 may be able to recommend a content related to ‘President LEE Myung Bak’ to a user. Thus, an operation of recommending a related content shall be described with reference to
In the above example, assume that the controller 180 extracts a keyword ‘President LEE Myung Bak’ on the assumption that a content for ‘President LEE Myung Bak’ is included in a user's conversation with a call counterpart. Subsequently, if the user activates a news application (or, a news webpage is outputted from activation of a web browser application), the controller 180 can identifiably display contents associated with the extracted keyword ‘President LEE Myung Bak’. Meanwhile, one example of the operation of identifiably displaying a recommended content is described with reference to
So far, according to the former embodiments described with reference to
According to one embodiment of the present invention, conditions considered in controlling a power of each of sensors may include a current remaining power level of the mobile terminal 100 and/or an amount of a learned use pattern.
Consideration of a Remaining Power Level
If a remaining power level of the mobile terminal 100 is enough, the controller 180 can detect a use pattern by fully activating all sensors. In particular, if the remaining power level is equal to or greater than a prescribed value, the controller 180 can activate all sensors. Subsequently, the controller 180 learns a user's use pattern with high accuracy/precision through the activated sensors and is then able to report a result of the learning to a server.
If the remaining power level of the mobile terminal 100 is not enough, the controller 180 can minimize a power consumed for use pattern detection by controlling power levels of the sensors. Two kinds of methods are proposed as a method of controlling power levels of sensors. According to a 1st method, if a sensor configured to consume a high power and a sensor configured to consume a low power exist in sensors capable of performing similar functions, a user pattern is detected using the sensor configured to consume a low power rather than the sensor configured to consume a high power.
For instance, sensors configured to detect a motion of the mobile terminal 100 may include a gyro sensor and an accelerometer sensor. In particular, the gyro sensor is able to measure an inclination of the mobile terminal 100 and consumes a power more than that of the other. The accelerometer sensor is able to measure an acceleration variation of the mobile terminal 100 and consumes a power relatively smaller than that of the gyro sensor. Each of the two sensors can detect a motion of the mobile terminal 100. And, the two sensors can analyze similar patterns despite differing from each other in detailed functions.
For another instance, as one example of a sensor capable of obtaining a location information of the mobile terminal 100, there may be a GPS (global positioning system) sensor. The GPS sensor has an advantage of measuring the location information of the mobile terminal 100 accurately but has a disadvantage of consuming a high power. As another example of a method of obtaining a location information of the mobile terminal 100, there is a method of obtaining a location information of a cell ID (cell info) or a Wi-Fi access point (AP). Although the location information obtained by this method may not be accurate than the location information measured by the GPS sensor, this method consumes a power less than that of the case of utilizing the GPS sensor.
Particularly, a recently issued bio sensor has such a power difference. ECG (electrocardiogram) sensor or PPG sensor has a relatively high power consumption but has a relatively low power consumption in measuring BPM (beats per minute), HRV (heart rate variability), RRI or the like.
If the circumstance cognitive level corresponds to the 1st level, while all kinds of sensors are activated, it is able to recognize circumstances. Hence, a precise use pattern is obtained by utilizing the methods 901 to 906 and can be then sent to a server.
If the circumstance cognitive level corresponds to the 2nd level, the sensors corresponding to the high power consuming methods are deactivated but the sensors corresponding to the low power consuming methods are activated only. Although the precision of the obtained use pattern may be lowered, this method can be appropriate for a case that a remaining power level is low.
Finally, if the circumstance cognitive level corresponds to the 3rd level, an operation of obtaining and analyzing a use pattern may not be performed by deactivating all sensors. Yet, if a previously learned use pattern is saved in a server, it may be able to perform an operation using the previously saved use pattern only.
According to a 2nd method, a rarely used sensor is deactivated using a previous use pattern. For instance, assume that working hours on weekdays are regular and that a location of the mobile terminal 100 is not changed during the working hours. If so, sensors for obtaining location information using GPS sensor and/or cell ID may be unnecessary. Hence, if it is determined that a remaining power level is not enough, the controller 180 can minimize waste of power by deactivating the corresponding sensors during the working hours on weekdays.
Amount of Learned Use Pattern
A method of controlling powers of sensors in consideration of an amount of a learned use pattern is described as follows. First of all, if an amount of a learned use pattern is enough to create a DB, it may be unnecessary to further learn a use pattern irrespective of whether a remaining power level is enough. In this case, it may be appropriate for the mobile terminal 100 to provide a user with an operation of utilizing a learned use pattern only rather than to learn a use pattern. Therefore, according to one embodiment of the present invention, as the learned use pattern amount saved in a server is equal to or greater than a predetermined count, if the controller 180 determines that the learned user pattern amount is enough, the controller 180 deactivates sensors and may not perform an operation of obtaining a use pattern, analyzing the obtained use pattern, and then reporting the analysis to a server.
If the controller 180 determines that a use pattern for a current place and/or time is not enough, the controller 180 activates sensors and is then able to perform an operation of obtaining a use pattern using the activated sensors and then reporting the obtained use pattern to the server.
Meanwhile, according to the above-described embodiment, activation/deactivation of sensors is explained. The activation/deactivation includes an operation of controlling whether to cut/allow powers self-used by sensors and is also able to indicate an operation of controlling whether to analyze a sensing signal despite that a power is used by a sensor in itself. In particular, if the controller 180 deactivates a prescribed sensor, it may mean that the controller 180 cuts off a power for the prescribed sensor and that the controller does not analyze a sensing signal detected from the prescribed sensor despite not cutting off the power for the prescribed sensor. The reason for this is that a power consumption for an operation of analyzing a sensing signal by an AP (application processor) is considerable despite that the prescribed sensor has a negligible power consumption difference between cutting off a power for the prescribed sensor and allowing a power for the prescribed sensor.
Therefore, according to one embodiment of the present invention, the controller 180 controls MCU (micro controller unit) for controlling sensors to be configured separately from AP (application processor). The MCU controls the sensors to detect sensing signals. And, the AP can analyze the detected sensing signals. Moreover, deactivation of a prescribed sensor can be replaced by not performing an analysis operation by the AP.
Accordingly, embodiments of the present invention provide various effects and/or features.
According to at least one of embodiments of the present invention, user's intention can be determined by actively utilizing various types of sensors provided to a terminal.
